Key Concepts

  • Input and Output
  • Rule (Addition or Subtraction)
  • Function Tables

Learning Objectives

  • Students will be able to define input and output in the context of a function table.
  • Students will be able to identify the rule (addition or subtraction) in a function table.
  • Students will be able to complete a function table by applying the identified rule.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students if they've ever used a machine that changes something (e.g., a vending machine). Introduce the idea of 'input' as what goes into the machine and 'output' as what comes out. Connect this to math by saying they'll be looking at number machines!
  • Video Viewing (7 mins)
    Play the 'Input and Output Tables - Find the Rule' video from Kids Academy. Encourage students to pay attention to how Teacher Michael explains input, output, and how to find the rule.
  • Discussion (5 mins)
    After the video, discuss what input and output mean. Ask students to explain how Teacher Michael found the rule in the video. Reiterate the concepts using simpler language if needed.
  • Practice Activity: Robot Rule Tables (10 mins)
    Distribute worksheets with blank input/output tables and possible rules (+1, +3, -2, -1). Have students work in pairs to fill in the tables and identify the correct rule. Design the worksheets using a fun robot theme, similar to the video.
  • Wrap-up (3 mins)
    Review the key concepts of input, output, and rule. Ask students to give real-life examples of input/output scenarios.

Interactive Exercises

  • Number Machine Game
    Create a simple 'number machine' using a cardboard box. Write a rule on the box (e.g., +3). Students whisper a number (input) into the box, and another student has to say the correct output based on the rule. Rotate roles.

Discussion Questions

  • What does 'input' mean in our number machine?
  • What does 'output' mean in our number machine?
  • How can we find the 'rule' that changes the input to the output?
  • Can you think of a real-life example of something going 'in' and something different coming 'out'?

Skills Developed

  • Addition and Subtraction
  • Problem-Solving
  • Pattern Recognition

Educational Standards

CCSS.Math.Content.1.OA.D.8:Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = _ - 3, 6 + 6 = _. CCSS.Math.Content.1.OA.C.6:Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13). CCSS.Math.Content.1.OA.A.1:Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
